LabVIEW DATA TYPES

Numeric- This data type contains either an integer or floating point.

Boolean - This data type contains logical combinations of TRUE/FALSE,AND OR NOT Etc.

String - Contains alpha-numeric characters only

Dynamic - Data associated with a signal and the attributes that provideinformation about the signal, such as the name of the signal or the dateand time the data was acquired.

Cluster - Encloses several data types. Cluster data types appear brown

if all elements in the cluster are numeric or pink if all elements of thec us er are o eren ypes.

These data types can be in either Scalar, 1D Array or 2D Array form.

Numeric DATA TYPE

The numeric data type represents numbers of various types.

Numeric DATA TYPE

Numeric Conversion

When different representation types are wired to the inputs ofa function, the function returns an output in the larger or wider

format. LabVIEW chooses the representation that uses more

.

The functions force the smaller representations to larger

dot on the terminal where the conversion takes place

Boolean DATA TYPE


11/23

Boolean DATA TYPE LabVIEW stores Boolean data as 8-bit values.

If the 8-bit value is zero, the Boolean value is FALSE.

Any nonzero value represents TRUE.

oo ean va ues a so ave a mec an ca act on assoc ate w t t em.

The two ma or actions are latch and switch.

Latch action is similar to a doorbell, whereas

switch action is similar to a light switch.

You can also define when the switch or latch occurs:

w en presse , w en re ease , or un re ease .

On the block diagram, strings are represented with the color pink.

D namic DATA TYPES

gna s genera e or acqu re y an xpress .

Data associated with a signal and the attributes that provide information about the signal,

such as the name of the signal or the date and time the data was acquired

You can wire the dynamic data type to any indicator or input that accepts numeric,

waveform, or Boolean data.

Use the Convert from Dynamic Data Express VI to convert dynamic data to numeric,

waveform, and array data types for use with other VIs and functions.

The following table lists indicators that accept the dynamic data type and the type ofdata the dynamic data type can contain, and describes how indicators handle the data.
